Chemical Structure

Pregabalin Impurity 54 CAS 616-42-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 110.13 g/mol gives Pregabalin Impurity 54 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Pregabalin Impurity 54 (CAS 616-42-2), a pharmacopoeial impurity reference standard (molecular formula C2H6O3S, MW 110.13 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a sulfone group, a carboxylic acid group, an ether linkage, Pregabalin Impurity 54 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 110.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Pregabalin Impurity 54 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
